I have a new 2014 PROSTAR 5.7 and when I engage the transmission slightly you can hear a high pitch whine as I power up it goes away, any thoughts would be appreciated, 65k was a lot to spend and I freaked a little when I heard this sound.

My 2010 did this when I first bought it as well. I think it just went away after a while.

Welcome to Team Talk. Sorry to hear it is a strange noise bringing you here. Have you called your dealer yet?

The possessive pronouns in this sentence just make me chuckle.



As for your problem... Is the whine in forward, reverse, or both?

I have the same issue with my boat. I thought it was the strut bearing going out or perhaps engine alignment. After I did all that work, I ended up switching to a different prop and the sound went away. Both props are balanced and have never been damaged or repaired, but the one has a slight whine from idle to abould 1500 rpms.

As other have said, on a new boat, take it to the dealer and let them tell you it is nothing to worry about.

I have been told a faulty PCV valve can sometimes make a similar noise, but have no direct experience.

... when I engage the transmission slightly ....

Have you tried doing this in neutral? So as to rule out the engine alone.

Same here. I had the prop reworked and then the whine/ring started. I filed the edges of each blade flat and that eliminated the sound.

Like mentioned it sounds like it's probably prop sing if in forward. I've had a prop do that on mine too. Have your dealer or another knowledgeable inboarder do a ride along to help verify. Otherwise try and borrow a prop to test. Doesn't even have to be 100% correct pitch, just test at low speed and low rpm only.



Direct drive boats almost always whine in reverse, that's totally normal.

This has come up somewhere on here before. Without hearing it in person I can't tell you 100% this is your issue, however this was my experience on my '09 X2, with the ZF Hurth trans.

High pitch whine at low RPM's, pretty sure it is the tranny, the tech bulletin back then was to replace the ATF with motor oil to help lesson the issue. I don't think there is any performance issue, just a slight annoyance.

My boat had 15W 40 in the trans from day one, had the whine from day one and I never had any tranny issues for 385 hrs until I sold the boat. I still hear from the new owner and he has not mentioned any tranny issues. It was a little more apparent if the level was a bit low also. I had several props, re-worked etc. and it was always there, just got used to it.

Ilmor is back to ATF, I don't notice it on my X25 with the 6.2:D

Forward only, engine noise for sure.

With such a sweet ride, I would check the PCV valve, and although I am not totally up to speed on the Ilmor engines, I would rule out any other possible vacuum type leaks, a small air leak?

Dealer should weigh in .......

although a "whine" could be me on shore watching you pull away in that sweet boat. ;)

Best of luck and keep us posted ....

I also started hearing this with our 98' 205 after we had a prop fixed.

Our 05 X9 did this too. Only in forward, reverse noise form the DD covered the whine. The dealer smoothed out the prop and the whine went away. It was a long time ago, but I think the whine is caused by the little ridges on the prop.

sorry to derail again, but i'm kinda sick of seeing this about Aric.

I grew up with boats that were my dads. I hate to break it to everyone, but my father explicitly told me; "This is your boat, treat it like you bought it, or lose it." It was always referred to as my boat even when he was standing in front of me. Thats the way he wanted it. It sure wasn't a MC X15 either. My guess is his father treats him the same as mine did for me.

That was the point I was trying to make. I was not trying to bash him just give some advice to stop the "you mean you parents boat" thing.

Knox, I accidentally quoted you. I understood your post. I was supposed to quote Mzimme.
Edit: Which that post I didn't think was that bad either.

Thanks Traxx. :) Back to the OP topic.:D Thread jack over:rolleyes:

If Aric gets married to a lady like mine, he won't get away with calling anything "mine"..... My wife has a way of correcting me ANYTIME I say "my".... It's "OURS":)


As far as the whine sound on the op boat----call Eric at Oj ask him if he can fix a "singing prop". Otherwise I'd assume you are under warranty---so talk to your dealer and then run it like you stole it!!! If it breaks.........time for W-claim...

Now that's pretty interesting right there - Thanks for posting.

On mine - I always thought it was the tranny, since I read it "here" :rolleyes: Could have been the prop??? I had 2 OJ's, same diameter and pitch, both had been reworked at least once, never went away. I would explain my sound exactly as they state in this article.

Why do we need to bash anyone on this forum unless the directly insult someone?

I don't there's anyone this forum that deserves to be flamed just for saying "my"...

FWIW, I noticed a high pitch whine on the '14 prostar I was in (Brooks Wilson's ski school). He didn't seem concerned about it but it was the same as you describe, just after putting it in forward.

On my 08, heard same noise. Dealer told me it was the prop singing (new 5 blade). Turned out it was the coupler needed to be adjusted.

My 6.2l ilmor makes the same high pitch whine your talking about. My dealer said it's something to do with the belts that ilmor uses. It's goes away once you hit the throttle. I haven't had any problems with the engine though.
